some, though not all, of what was said; the old lady's words were punctuated by noise from outside, from the aircraft engines, which were being started. "Excuse... my son just boarded... blond hair, no hat, camel-hair coat... forgot his wallet... all his money." The old lady, Standish observed, was holding what looked like a man's billfold.
The gate agent glanced up impatiently. He appeared harassed; gate men usually were at the last moments of departure. The agent put out his hand to take the wallet, then, observing the old lady, changed his mind and said something quickly. He pointed to the tourist boarding walkway and Standish heard, "Ask a stewardess." The old lady smiled and nodded, and entered the walkway. A moment later she was out of sight.
All that Customs Inspector Standish had observed had taken only moments---perhaps less than a minute. Now, he saw a newcomer arrive---a stoop-shouldered, spindly man, hurrying down Concourse "D" toward gate forty-seven. The man had a gaunt face and a slight sandy mustache. He was carrying a small attache case.
Standish had been about to turn away, but something about the man attracted his attention. It was the way the newcomer was holding his case---under his arm, protectively. Harry Standish had watched people, many times, doing the same thing as they came through Customs. It was a giveaway that whatever was inside the case was something they wanted to conceal. If this man had been coming in from overseas, Standish would have had him open the case, and would have examined its contents. But the man was goingout of the United States.
Strictly speaking, it was none of Harry Standish's business.
Yet something... instinct, a sixth sense which Customs men developed, plus a personal connection, through Judy, with Flight Two... something kept the inspector watching, his eyes directed at the small attache case which the spindly man still cradled.
THE FEELING of confidence which returned to D. O. Guerrero at the insurance counter had remained. As he approached gate forty-seven, observing that he was still in time for Flight Two, he had a conviction that most of his difficulties were over; from now on, he assured himself, everything would work out as he had foreseen. In keeping with this belief, there was no problem at the gate. As he had planned from the beginning, at this point he drew attention to the minor discrepancy between the name "Buerrero" on his ticket and "Guerrero" on his passport. Barely glancing at the passport, the gate agent corrected both the ticket and his passenger list, then apologized, "Sorry, sir; sometimes our reservation machines get careless." Now, Guerrero noted with satisfaction, his name was recorded properly; later, when Flight Two was reported missing, there would be no doubt about his own identification.
"Have a pleasant flight, sir." The gate agent returned his ticket folder and motioned toward the tourist section walkway.
As D. O. Guerrero went aboard, still holding his attache case carefully, the starboard engines were already running.
His numbered seat---by a window in a three-seat seetion---had been allocated when he checked in downtown. A stewardess directed him to it. Another male passenger, already in the aisle seat, stood up partially as Guerrero squeezed by. The center seat, between them, was unoccupied.
D. O. Guerrero balanced his case cautiously on his knees as he strapped himself in. His seat was midway in the tourist section, on the left side. Elsewhere in the cabin, other passengers were still settling down, arranging hand baggage and clothing; a few people were blocking the center aisle. One of the stewardesses, her lips moving silently, and looking as if she wished everyone would keep still, was making a count of heads.
Relaxing for the first time since leaving the South Side apartment, D. O. Guerrero leaned back in his seat and closed his eyes. His hands, steadier than at any other time this evening, were firmly on the attache case. Without opening his eyes, his fingers groped under the handle and located the all-important loop of string. The feel of it was reassuring. He would sit precisely like this, he decided, when in approximately four hours from now he would pull the string, releasing the electrical current which would fire the massive charge of dynamite within the case. When the moment came, he wondered, how much would he have time to know? In answer, he reasoned: there would be an instant... one fleeting particle of a second only... when he would savor, triumphantly, the knowledge of success. Then, mercifully, no more...
Now that
